Definitions

  • the present invention relates to a method of and an apparatus for feeding a scanned medium in an auxiliary direction with a rotatable feed drum and two nip rollers which sandwich the scanned medium.
  • a light beam emitted by a light beam generator is applied to scan a medium in a main scanning direction by a light beam deflector and a scanning lens, and the scanned medium is fed in an auxiliary scanning direction substantially perpendicular to the main scanning direction by an auxiliary scanning mechanism for thereby recording an image on or reading an image from the scanned medium.
  • the auxiliary scanning mechanism which is of the type widely used in the art comprises a rotatable feed drum and two nip rollers movable toward and away from the rotatable feed drum for sandwiching a scanned medium for smoothly feeding the scanned medium in the auxiliary scanning direction.
  • the scanned medium While the scanned medium is being pressed against an outer circumferential surface of the feed drum by the two nip rollers or the scanned medium is being fed by rotation of the feed drum, the scanned medium often tends to slack due to gravity, curvature, or other external forces applied thereto. Therefore, the scanned medium as it is fed by the feed drum is liable to be lifted off the feed drum or move in a tortuous path. When the scanned medium is thus lifted off the feed drum or moves in a tortuous path, any straight line recorded on the scanned medium by exposure to a light beam is unduly curved in the direction in which the scanned medium is fed or in the direction transverse thereto.

  • rollers 92 will be held in direct rolling contact with the outer circumferential surface of the feed drum 32 outside of the transverse dimension of the film F for lifting the elongate lands 88a, 88b, 88c off the outer circumferential surface of the feed drum 32 by a predetermined distance H (see FIG. 1).
  • the guide mechanism 42 has a guide plate 96 fixed in position which extends axially of the feed drum 32.
  • the guide plate 96 has a plurality of separate plate-like pressers 100 having their tip ends positioned lower than the uppermost position of the outer circumferential surface of the feed drum 32.
  • the film feeder and cutter 18 comprises a plurality of guide plates 110, second and third feed roller pairs 112, 114 spaced from each other, and a cutter 116 disposed between the second and third feed roller pairs 112, 114.

  • the spur gears 56 mounted on the rotatable shaft 54 rotate, elevating the racks 58 meshing therewith and the brackets 44, 46 to which the racks 58 are fixed.
  • the first and second nip rollers 34, 36 placed on the shoulders 60a, 60b of the brackets 44, 46 are now lifted off the feed drum 32, with the first nip roller 34 supported lower than the second nip roller 36 (see FIG. 4).
  • the upstream and downstream guide plates 68a, 68b are angularly moved upwardly by the links 76, 78, and kept in a desired attitude.
  • the swingable guide plate 120 is swung upwardly about the shafts 118 by engagement with the downstream engaging fingers 98 of the brackets 44, 46, and the driven roller 112b supported on the swingable guide plate 120 is moved upwardly away from the drive roller 112a.
  • the ascending movement of the brackets 44, 46 causes the arms 86 of the winding mechanism 40 to ascend in unison with the second nip roller 36 with the ends 86a engaged by the rotatable shaft 54. Therefore, the other ends 86b of the arms 86 are angularly moved upwardly about the rotatable shaft 54, and the guide bar 80 fixed to the arms 86 is moved along an arcuate path away from the outer circumferential surface of the feed drum 32.
  • the leading end of the film F is guided by the plate-like pressers 100 to move toward the feed drum 32. Because the tip ends of the plate-like pressers 100 are positioned lower than the uppermost position of the outer circumferential surface of the feed drum 32, the leading end of the film F is reliably brought into contact with the outer circumferential surface of the feed drum 32 (see FIG. 4).
  • the stepping motor 48 is now reversed to rotate the rotatable shaft 54 in the direction indicated by the arrow Y (FIG. 2), whereupon the brackets 44, 46 start descending (see FIG. 5).
  • the brackets 44, 46 move downwardly, the first and second nip rollers 34, 36 placed on the shoulders 60a, 60b are lowered.
  • the second nip roller 36 is placed on the outer circumferential surface of the feed drum 32 by gravity, sandwiching the leading end of the film F between the feed drum 32 and the second nip roller 36 (see FIG. 6).
  • the arms 86 descend in unison with the first nip roller 34 with the ends 86a borne by the rotatable shaft 54, angularly displacing the other ends 86b toward the outer circumferential surface of the feed drum 32. Therefore, the guide bar 80 secured to the arms 86 moves along the arcuate path toward the feed drum 32 until the rollers 92 are held against the outer circumferential surface of the feed drum 32.
  • the elongate lands 88a, 88b, 88c of the guide bar 80 are spaced from the outer circumferential surface of the feed drum 32 by a predetermined distance H.
  • the brackets 44, 46 further descend, the first nip roller 34 contacts the outer circumferential surface of the feed drum 32 due to gravity, sandwiching the film F between the first nip roller 34 and the outer circumferential surface of the feed drum 32 (see FIG. 7).
  • the film F When the film F is fed toward the recorder 16 in response to rotation of the first feed roller pair 26, the film F is drawn by a length required to record an image thereon between the feed drum 32 and the first feed roller pair 26, with the result that the guide mechanism 42 is spaced from the feed path of the film F (see FIG. 1).
  • the first feed roller pair 26 is then stopped against rotation, and the feed drum 32 is rotated about its own axis in the direction indicated by the arrow at a relatively low speed.
  • the film F is now fed in the auxiliary scanning direction indicated by the arrow A while being sandwiched between the feed drum 32 and the first and second nip rollers 34, 36.
  • the film F is scanned in the main scanning direction by the light beam L emitted from the light beam generator 12 and modulated by image information.
  • an image represented by the image information is two-dimensionally recorded on the film F.
  • the first and second nip rollers 34, 36 placed respectively on the shoulders 60a, 60b of the brackets 44, 46 are disposed in different vertical positions, respectively.
  • the brackets 44, 46 are lowered, the film F which has been brought into contact with the outer circumferential surface of the feed drum 32 by being guided by the plate-like pressers 100 of the guide mechanism 42, is sandwiched first at its leading end between the second nip roller 36 and the feed drum 32, and then at its upstream portion between the first nip roller 34 and the feed drum 32.
  • the film F is reliably prevented from being displaced off the outer circumferential surface of the feed drum 32 between the first nip roller 34 and the second nip roller 36. Since the film F is thus held in intimate contact with the outer circumferential surface of the feed drum 32, any straight line recorded on the film F by exposure to the light beam L is prevented from being unduly curved.
  • the second nip roller 36 is made of rubber and the first nip roller 34 is made of a metal such as aluminum, so that the second nip roller 36 exerts feeding forces greater than feeding forces that can be exerted by the first nip roller 34. Therefore, when the feed drum 32 is rotated in the direction indicated by the arrow, the film A can reliably be fed in the direction indicated by the arrow A by the second nip roller 36 which is held in rolling contact with the outer circumferential surface of the feed drum 32 by gravity. The film F is thus not lifted off the outer circumferential surface of the feed drum 32 while being fed between the second nip roller 36 and the first nip roller 34.
  • the feeding forces exerted by the second nip roller 36 are made greater than the feeding forces exerted by the first nip roller 34 because the second nip roller 36 is made of rubber and the first nip roller 34 is made of a metal such as aluminum.
  • the feeding forces exerted by the second nip roller 36 may be made greater than the feeding forces exerted by the first nip roller 34 by making the second nip roller 36 heavier than the first nip roller 34.
  • the second nip roller 36 having an outer layer made of rubber is 1.5 to 3 times heavier than the first nip roller 34 made of aluminum.
  • the film F is accurately fed in the direction indicated by the arrow A while being pressed against the outer circumferential surface of the feed drum 32 between the first and second nip rollers 34, 36.
  • any straight line recorded on the film F by exposure to the light beam L is prevented from being unduly curved, and any image can precisely be recorded on the film F which is being fed by the feed drum 32 and the first and second nip rollers 34, 36.
  • the winding mechanism 40 is positioned downstream of the second nip roller 36 with respect to the auxiliary scanning direction.
  • the guide bar 80 of the winding mechanism 40 has its elongate lands 88a, 88b, 88c spaced a distance H from the outer circumferential surface of the feed drum 32 by the rollers 92 on the backup rod 90.
  • the distance H is set to 1 ⁇ 2 mm, for example, depending on the thickness of the film F.
  • the winding mechanism 40 is effective in winding the film F around the outer circumferential surface of the feed drum 32 through an angle ⁇ of 70°, for example, from the exposure position where the light beam L is applied to the film F to a position downstream of the second nip roller 36 in the auxiliary scanning direction. Consequently, the second nip roller 36 remains in constant contact with the film F continuously from the time when an image starts being recorded on the film F to the time when the recording of the image on the film F is finished. The image can thus be recorded under constant conditions on the film F.
  • Another advantage offered by the winding mechanism 40 is that inasmuch as the film F is held in contact with a relatively large area of the outer circumferential surface of the feed drum 32, the feed drum 32 can exert relatively large feeding forces to the film F.
  • the recorded film F While an image is being recorded on the film F, the recorded film F is accommodated between the second feed roller pair 112 and the feed drum 32. After the image has been recorded on the film F, the first feed roller pair 26, the feed drum 32, the second feed roller pair 112, the third feed roller pair 114, and the fourth feed roller pair 124 are simultaneously rotated to feed the film F to move an end of the recorded region of the film F toward the shutter 126.
  • the cutter 116 is actuated to cut off the film F to a predetermined length which contains the recorded region, after which the shutter 126 is opened and the severed recorded film F is delivered by the fourth feed roller 124 into the image developing apparatus. An unrecorded region of the film F which remains in the recorder 16 is fed back into the magazine 22.
  • a movable guide mechanism may be employed which can be retracted away from the feed path of the film F.
  • the feeding apparatus and the feeding method according to the present invention may be incorporated in a reading apparatus which applies a light beam to an original (film) with image information recorded thereon for photoelectrically reading the recorded image information.
  • the scanned medium Since the leading end of a scanned medium is smoothly brought into rolling contact with the outer circumferential surface of the feed drum by being guided by the guide mechanism, the scanned medium is reliably held on the outer circumferential surface of the feed drum by the first and second nip rollers. The scanned medium is thus reliably prevented from being lifted off the outer circumferential surface of the feed drum between the first and second nip rollers.
  • the scanned medium is prevented from being lifted or tortured between the first and second nip rollers. Consequently, the scanned medium can be fed highly precisely in the auxiliary scanning direction through a relatively simple mechanical arrangement.
